Life Cycle Analysis

Eco-design material :

Arch. Maria Chiara Pastore of Stefano Boeri Architetti, famous for creating the vertical forests model for sustainable residential buildings embodied by Milan’s Bosco Verticale (Vertical Forest), emphasized how its vegetal system contributes to the construction of a microclimate, produces humidity, absorbs CO2 and dust particles and produces oxygen.

This is not only instrumental in curbing climate change but also utilises accessible building materials for large-scale construction projects. Compared to concrete, steel, cement and glass, wood requires less energy to produce and stores – rather than emits - carbon.

Dr Michael Ramage, Director of the Centre for Natural Material Innovation at the University of Cambridge, instrumental in the design of the “The Toothpick” (a wooden skyscraper set to become the second tallest building in London), discussed “super-tall timber”. He explained how wood construction involves cross-laminated timber, a material made of many sheets of wood glued and compressed together, is stronger than steel and a viable candidate for building skyscrapers

Indoor Air quality

Integrating urban forests into architecture leads to breathtaking results. Sometimes referred to as treescrapers, these buildings have plenty to offer beyond their unique architecture. Implementing sustainable principles, they are a breath of fresh air in high density cities — literally. Urban forests provide us with better air quality by increasing the available oxygen. Also, they ensure a safe habitat for animals that in most cases wouldn’t survive the harsh conditions of crowded cities.
